Description Adrian Bassett 2008-10-27 14:57:16 UTC

With portage 2.2_rc12:

[ebuild   R   ] sys-apps/portage-2.2_rc12  USE="doc -build -epydoc (-selinux)" LINGUAS="-pl" 0 kB

After a long compile to upgrade gcc to 4.3.2 from 4.3.1:

[ebuild  NS   ] sys-devel/gcc-4.3.2 [3.3.6-r1, 4.2.2, 4.2.3, 4.2.4, 4.3.1-r1] USE="fortran gcj gtk (multilib) multislot nls objc objc++ objc-gc openmp (-altivec) -bootstrap -build -doc (-fixed-point) (-hardened) -ip28 -ip32r10k -libffi -mudflap (-n32) (-n64) -nocxx -test -vanilla" 0 kB

installation failed because of detected file collision:

* Searching all installed packages for file collisions...
* 
* Press Ctrl-C to Stop
* 
* sys-devel/gcc-4.2.4
* 	/usr/lib64/security/classpath.security
* 
* sys-devel/gcc-4.3.1-r1
* 	/usr/lib/pkgconfig/libgcj-4.3.pc
* 	/usr/lib64/security/classpath.security
* 
* sys-devel/gcc-4.2.3
* 	/usr/lib64/security/classpath.security
* 
* sys-devel/gcc-4.2.2
* 	/usr/lib64/security/classpath.security

which is fair enough because collision-protect is set in FEATURES in /etc/make.conf.

However, rather than a complete re-compile after editing /etc/make.conf to remove collision-protect from the list of FEATURES (or the equivalent of prepending it to the emerge command environment, i.e. FEATURES="-collision-protect" emerge gcc), I tried using the lower-level ebuild command itself to complete the installation.

But

FEATURES="-collision-protect" PORTAGE_TMPDIR=/var/tmp ebuild gcc-4.3.2.ebuild qmerge

failed with the same file collision detection messages.

I managed to make a package:

FEATURES="-collision-protect" PORTAGE_TMPDIR=/var/tmp ebuild gcc-4.3.2.ebuild package

but 

FEATURES="-collision-protect" emerge -k =sys-devel/gcc-4.3.2

again failed with the same file collision errors.

Using the latest stable version of portage (2.1.5.6) allowed the 'ebuild ... qmerge' command to work as expected whilst the 'emerge -k ...' command also completed OK with portage 2.2_rc11, so it looks as if the bug is between rc11 and rc12 of portage 2.2.

Many thanks.

Consider that a very useful feature for now.
